Neurochips detect brain's reaction to learning

Harnessing the photoconductive properties of novel silicon "neurochips,"
researchers at the University of California, San Diego have been able to
directly observe the physical changes that neurons undergo during learning.
By non-invasively firing specific neurons grown on a silicon substrate, the
researchers were able to identify the exact physical changes, which were
observed with a fluorescent tracer. Laboratory observations during learning
regimes were able to verify the specific physical changes resulting in short-
and long-term memories.
